Space Reflection #3

http://www.abc.net.au/btn/story/s3693796.htm

This article was about how 3 years ago a meteor nearly hit Russia.

In 2013 a meteor nearly hit Russia, It was big and got far into the earth’s atmosphere, but the force was apparently 20X bigger than an atomic bomb, which is an unbelievable force because it didn’t even hit the ground and it got that much power from just falling, imagine if it actually hit the ground generating more force and making a MASSIVE explosion. Although it did not hit the earth’s crust  due to that it burned up before it could make contact with the ground. But what is the difference between meteors, meteorites, comets, etc. A comet is a chunk of ice and dust from the farther parts of the solar system; this is probably because it was very cold, but if comets are made of ice, where did the water come from? But although for some reason we call the hunks of metal that actually come in contact with our planet meteorites, instead of meteors; the one that don’t come in contact with out planet.

Space Reflection #2

This article was about mixed facts about the solar system and its planets.

The solar system is a series of objects that orbit the sun due to the means of gravity. The way that they suppose earth will end is when the sun burns out of energy, swelling up. This can either engulf earth entirely or just nearly completely melt the crust. That it will shrink down into a white dwarf and all the planets will depart from the suns orbit drifting away. Although on the internet I heard that it will swell up into a red giant star and the explode causing a supernova, or collapse on itself creating a black hole. Another interesting fact is that the sun makes up approximately 99.87% of the solar systems mass. This is a gigantic amount. And the earth doesn’t even take up all that much. It’s more of a tiny speck, with Jupiter taking up most of the remaining mass. If earth was created before the sun was created, what happened to the earth before it came part of the solar system and it started to orbit the sun?

Space Reflection #1

This Article, that can be found on my teachers ‘blog; antsclass. Is about how 3 different ancient civilisations discovered different things about astronomy.
There were 3 different civilisations that found out a few things about astronomy, Babylon, Maya and the Greeks. Babylon had discovered how to make such things as calendars and such, but I would also believe they created the system of how time works. An astrologer by the name of tamely that was born in Egypt while under the rule of the romans, discovered a system called the `Ptolemaic system`, which suggested that the earth was in the centre of the solar system which many believed, but now it is deemed false. Although he got a lot of his knowledge from a man called hiparcus. A question that I have and am sure a lot of other people have is how did they figure all this out in the ancient times, even if it was incorrect?

Science Goals For Term 4

For our topic this term we are doing a science unit about space, because this is our topic, these are a few goals that i have set for myself.

Science As a Human Endeavour

As one of my goals about space, I want to know how gravitational waves affect our lives and how they work and what their effect is.

And I also want to know about how the moon affects tides of the ocean.

Earth and Space Sciences

About how the earth works, I would like that know what makes earth orbit the sun like it does and what gravitational pulls are.

Science Inquiry Skills

To help me with these goals I would like to be able to use graphs, tables, observations, etc. to discover patterns and create relationships of information gained from other lessons and experiments.

Goals I have Achieved and Where to Next

I have not learnt about ratios and scales and also how to find out the area of a curved shape due to the fact that I haven’t been taught them during class time. But what I did learn was how to convert from fractions, decimals and percentage when I was learning in class and also revision from last year. I didn’t learn about sound and the human body but on the up side we did learn about natural disasters another area of science and we learnt that through our integrated studies unit through making an information text. We didn’t have a topic on history so we didn’t learn about history nor did we work all that much on narratives for unknown reasons.

Due to the fact that our topic this term is about space, something I would like to improve on in the future is; a lot of random facts about space, because I don’t know all that much about space at the moment, I can’t really say what I would like to learn about, I would like to learn about anything really. I would also like to revise bidmas and do some pretty tricky equations. I also find shapes and angles would be very interesting so I would like to learn about that, and finally I would like to learn to make a map which I think my teacher said we were doing.
